I think they dislike snake people - when I posted about frozen feeders on my local CL I got a ton of responses telling me I was evil and horrible person and they have mice as pets and I'm sick that I'd feed them to my snake...blah blah blah....
But that exchange was ridiculous, at no point did you say that you couldn't afford the prices, only that you were looking for a better deal. Everybody is always looking for a better deal on everything! Sorry they were such jerks to you.
